*) jails provide virtual hosting at native speed, but _only_ for FreeBSD
   guests.  i.e., you can't run Linux in a FreeBSD jail
*) qemu works well on FreeBSD in my experience, but there is a considerable
   performance hit.
*) Xen should give you what you want, but I've no information on the
   status of Xen on FreeBSD at this time.
